GOP presidential nominee Donald Trump travelled to Mexico on Wednesday to meet with Mexican President Enrique Peña Nieto. The surprise trip and initial details of the meeting were first confirmed by LifeZette.

Sources including Mexican officials involved in the planning of the visit, who spoke on the condition of anonymity, stated the meeting would cover a broad variety of topics ranging from trade to security to immigration and the contentious issue of border enforcement.

Trump adviser and former New York City Mayor Rudy Giuliani, Republican National Committee Chairman Reince Priebus and Alabama Sen. Jeff Sessions, along with high-ranking Mexican officials, were expected to attend the meeting.

The meeting was ultimately agreed to despite concerns from both Mexican security services and the U.S. Secret Service.
